Technical Abstract:
Mixed multifloral rose and strawberry gardens planted adjacent to pome fruit orchards continue to support the non-pest, strawberry leafroller, Ancylis comptana, which acts as an overwintering host for the leafroller parasitoid, Colpoclypeus florus. As gardens matured they had more foliage, hosted more of the beneficial complex, and parasitism of pest leafrollers in the adjacent orchards increased in both spring and summer generations. OBLR and Pandemis pyrusana were equally susceptible to parasitism by C. florus in orchards adjacent to rose gardens.
